A case of Greenberg dysplasia [hydrops fetalis. ectopic calcifications, 'moth-eaten' skeletal dysplasia (HEM)] is presented. Fetal ultrasonography at 20 weeks' gestation showed hydrops fetalis, severe micromelia, irregular hyperechogenic foci in the ribs and vertebral bodies, irregular hypo- and hyperechogenic areas and abnormal contour within the long bones. and flattened and 'T'-shaped appearance of the vertebrae. Findings on postmortem histological and radiographic examination were consistent with Greenberg dysplasia. Copyright (C) 2001 John Wiley & Sons, Ltd.
